So, I have a couple idea for the game. Since the revolver (which its stock image are probably Colt Phyton) use 38 Specials, how about introducing heavy-armored bullet-resistance/ near bulletproof enemies with higher health than regular enemies and can tank 45-70 percent damage from 38. ( Knife deal standard damage just like on regular enemies.) The only insta-kill the heavies are 357 Magnum which basically can be fired in the same revolver. Make 357 harder to find in game (like police car event which 30 to 40 percent probality to get it alongside standard 38 or gasmask.) Or make it pricier to buy from probaly future-faction related to military or something.
